DETAILED DESCRIPTION

[0017] The embodiments of the utility model are described in detail below, refer to Figure 1 The embodiments of the utility model provide an automatic medicine drawing device, including: pneumatic pump support 100, pneumatic diaphragm pump 200, medicine barrel 300 and first pipeline 400, pneumatic pump support 100 is formed by multiple vertical and horizontal support rods 112, first platform 110 and second platform 120 are equipped in pneumatic pump support 100, pneumatic diaphragm pump 200 is fixed to first platform 110, medicine barrel 300 is horizontally placed on second platform 120, pneumatic diaphragm pump 200 is connected with medicine barrel 300 using first pipeline 400, first pipeline 400 has inclined part 111, and inclined part 111 is obliquely inserted into the barrel mouth of medicine barrel 300, and pneumatic diaphragm pump 200, visible volume barrel 500, medicine adding valve 600 and medicine liquid tank 700 are sequentially connected through second pipeline 410.The device uses pneumatic diaphragm pump 200 as power source, replaces traditional manual operation, avoids that operating personnel directly contact corrosive, high-risk chemical medicine liquid, greatly reduces the risk of chemical leakage or sputtering accident, and protects the personal safety of operating personnel.Visible volume barrel 500 used in the device has clear scale mark, can directly show the medicine liquid volume, and the operator can easily read and accurately control the adding amount of medicine liquid, avoids the problem of excessive or insufficient medicine liquid caused by human factors, improves the precision of medicine liquid adding, ensures the electroplating quality and the stability of production process.Through the inclined platform 120 of design, medicine barrel 300 can be placed at a certain angle, so that the medicine liquid can flow into pneumatic diaphragm pump 200 more smoothly, thereby minimizing the barrel bottom residual, improving the medicine liquid utilization rate, reducing resource waste and saving production cost.

[0018] Further, the pneumatic diaphragm pump 200 drives the compressed air to extract the liquid medicine from the medicine barrel 300 and deliver it to the dosing cylinder 500 through the first pipeline 400, and the pneumatic pump support 100 is used to bear the entire device, of course, the specific structure of the pneumatic pump support 100 is not limited in the utility model, preferably, the pneumatic pump support 100 is composed of a plurality of vertical and horizontal support rods 112, and the pneumatic pump support 100 also has a baffle 130 to prevent the medicine barrel 300 from tipping over during the medicine extraction process. In actual operation, the medicine barrel 300 may be displaced or tipped over due to external factors (such as vibration, collision) or internal liquid medicine shaking, which not only may cause liquid medicine leakage, environmental pollution and resource waste, but also may cause safety hazards to operators and equipment. The design of the baffle 130 effectively solves this problem, which provides additional support and protection for the medicine barrel 300, ensuring that the medicine barrel 300 remains stable during the entire medicine extraction process. Especially when the medicine barrel 300 is large or heavy, the role of the baffle 130 is particularly significant, which can prevent the medicine barrel 300 from accidentally sliding or falling over, ensuring the safety and continuity of operation. At the same time, the pneumatic pump support 100 is also provided with a liquid seepage prevention baffle 140 to prevent liquid from falling during the medicine extraction process. The design of the liquid seepage prevention baffle 140 is a structural improvement proposed to solve the problem of liquid dripping during the extraction process. In actual operation, even if a small amount of liquid medicine drips from the pipeline or interface, the liquid seepage prevention baffle 140 can effectively block these liquids from spreading to the ground or other equipment, avoiding unnecessary pollution and cleaning work. This is very important for maintaining a clean and safe working environment, especially when handling hazardous or flammable liquid medicine, the liquid seepage prevention baffle 140 can effectively reduce the risk of accidents and protect the health and safety of employees. Further, the specific positions of the first platform 110 and the second platform 120 are not limited in the utility model, preferably, the first platform 110 is located above the second platform 120, the first platform 110 is used to place the medicine barrel 300, and the second platform 120 is provided with a beaker 900.

[0019] Further, the pneumatic diaphragm pump 200 is connected with the bottom of the medicine barrel 300 through the first pipeline 400, so that the medicine liquid can be extracted from the bottom of the medicine barrel 300. The pneumatic diaphragm pump 200 is connected with the bottom of the medicine barrel 300 through the first pipeline 400, and this design allows the medicine liquid to be directly extracted from the bottom of the barrel. Compared with the traditional top extraction method, the bottom extraction can more thoroughly utilize the medicine liquid in the medicine barrel 300, reducing waste. Especially when the medicine barrel 300 is about to be used up, the bottom extraction can minimize the residual medicine liquid and improve the utilization rate of the medicine liquid. At the same time, the first pipeline 400 has an inclined portion 111, of course, the specific inclination angle of the inclined portion 111 is not limited in the utility model, and preferably, the inclination angle of the inclined portion 111 and the end surface of the barrel mouth is 25° to 60°. Considering the flowability of the medicine liquid and the influence of the internal structure of the medicine barrel 300, it is ensured that the medicine liquid can smoothly flow into the pipeline without generating excessive resistance. A proper inclination angle can help the medicine liquid overcome the action of gravity, especially when the amount of medicine liquid is small, and the effective extraction of the medicine liquid can also be ensured. The range of 25° to 60° has been verified by experiments, which can not only ensure the smooth flow of the medicine liquid into the pipeline, but also prevent the medicine liquid from splashing or overflowing due to too large an angle. This design not only improves the efficiency of medicine liquid extraction, but also reduces the residual medicine liquid in the medicine barrel 300, improving the resource utilization rate.

[0020] With reference to Figure 1, the inclined part 111 can be obliquely inserted into the barrel opening of the medicine barrel 300, which design can effectively extract the medicine liquid even when the amount of medicine liquid is small, reduce the residue of medicine liquid, and improve the resource utilization rate. Further, the pressure regulating valve 800 is arranged between the pneumatic diaphragm pump 200 and the medicine liquid tank 700, and the pressure regulating valve 800 is fixed on the oil-water separator back plate 810. The addition of the pressure regulating valve 800 is crucial for controlling the compressed air pressure entering the pneumatic diaphragm pump 200. It can adjust the working pressure of the pneumatic diaphragm pump 200 according to the actual needs, and ensure the stable operation of the pump under different working conditions. This is very important for keeping the constant and precision of the medicine liquid extraction speed, especially when dealing with sensitive chemical agents, accurate pressure control can avoid the problem of unstable medicine liquid flow caused by pressure fluctuation. At the same time, fixing the pressure regulating valve 800 on the oil-water separator back plate 810 not only saves space, but also facilitates maintenance and inspection, and ensures the long-term reliable operation of the equipment. In addition, the presence of the oil-water separator can prevent oil and water contained in the compressed air from entering the system, protect the internal components from contamination, and prolong the service life of the equipment. The specific material of the first pipeline 400 and the second pipeline 410 is not limited in the utility model, preferably, the first pipeline 400 and the second pipeline 410 are both made of polytetrafluoroethylene material. Polytetrafluoroethylene is known for its excellent chemical corrosion resistance, and is suitable for various strong acids, strong bases and other corrosive media, which ensures the reliability and safety of the pipeline in long-term use in harsh environments. In addition, polytetrafluoroethylene has a low friction coefficient, which makes the flow of medicine liquid in the pipeline more smooth, reduces the energy loss, and improves the transmission efficiency. At the same time, the non-stick property of polytetrafluoroethylene also helps to prevent the deposition of medicine liquid on the inner wall of the pipeline, reducing the cleaning difficulty and maintenance cost.

[0021] Further, the visible volume barrel 500 is provided with a scale mark. The setting of the scale mark enables the operator to intuitively observe and monitor the extraction amount of the medicine liquid, and ensures that the amount of medicine liquid added each time is accurate. This is particularly important for production processes that require strict control of the amount of medicine liquid. Further, the medicine valve 600 is provided with a manual / automatic control system. The specific control system of the medicine valve 600 is not limited in the utility model, and the medicine valve 600 can realize full automatic control on the production line with high automation, or can be switched to manual mode under the condition of manual intervention. The system can automatically complete the extraction and addition process of the medicine liquid according to the preset parameters, reduce the frequency and complexity of manual operation, and improve the production efficiency. In manual mode, the operator can directly control the on-off valve 600 to cope with unexpected situations or special needs, such as debugging the equipment, replacing the type of medicine liquid, etc.
